What we're building

GESTEL is a generative-AI creative production SaaS for e-commerce sellers, beauty brands, and fashion brands. We're working to dramatically cut the cost of commercial image shoots and lower the barrier to AI image generation. More than 2,000 commerce brands use it today.

조앤안AX (C&AX) is a done-for-you service that automates the repetitive ad operations of Korean commerce brands with AI: ad setup and review, daily reports, and budget alerts, built around each brand's workflow.
